The study will include 3800 intensive care patients who have septic shock. Each enrolled patient will be randomised to receive either Hydrocortisone 200mg or placebo daily for 7 days as a continuous intravenous infusion while in intensive care. The patient will be followed for 90 days. If the patient is discharged prior to 90 days a telephone call will be made for the followup information. At six months the patient will be contacted again for completion of a quality of life questionnaire.
